我通过使用'django-admin'命令来解决这个问题，如下所示:

Django-admin startproject _project_name

只需删除“django-admin”附加的“。py”

这是一个解释器错误。

如果你正在使用vscode，那么只需要遵循以下步骤:

视图 命令面板 搜索python 选择翻译 选择windows存储和你的问题将得到解决，几秒钟后，错误已经消失。

路径改变导致此问题。

================================== 解决方案 =========================================

第一个转到：虚拟环境

通过运行命令: 源bin /激活

然后安装django，因为你会得到与import django相关的错误:

pip install django

然后运行:

python manage.py runserver

(注意:请将'runserver'更改为您要运行的程序名称)

对于同样的问题，它在我的案例中起了作用。 ================================== 剧情简介 =========================================

祝你好运! !

我得到这个是因为我忘记了我安装Django使用pip -U，所以它只对运行我的Django应用程序的用户可用。要运行manage.py，我必须这么做

sudo su -s /bin/bash MY_DJANGO_USER
/PATH/TO/MY/APP/manage.py

对我来说，我的服务器使用的是Python 2.4。我只是查找了安装在我服务器上的Python 2.7，并创建了一个别名。

alias python=python2.7

如果你想知道更多，我在这里找到了解决方案

如果你像我一样，在virtualenv中运行django，并得到这个错误，请查看你的manage.py。 第一行应该定义用于运行脚本的python可执行文件。 这应该是你的virtualenv的python的路径，但它是错误的，如/usr/bin/python，这不是相同的路径，将使用全局python环境(包将丢失)。 只需将路径更改为virtualenv中python可执行文件的路径。

你也可以用#!/usr/bin/env python。这应该使用适当的python环境和解释器，前提是您首先激活了virtualenv(我假设您知道如何做到这一点)。
